  "textContent": "Various embodiments relate to a system and related method of validating a distance based on a plurality of sensor measurements in a vehicle. A tamper-proof odometer system may comprise an odometer and a tamper-proof sensor that independently determine distances based on measurements of vehicle components. The tamper-proof sensor may maintain a non-modifiable count based on the angular rotation of a target wheel from which to calculate a vehicle's distance travelled. An odometer may maintain a count based on the rotation of a wheel mounted to the transmission. An electronic control unit (ECU) or dashboard control unit (DCU) may compare the distance derived from the odometer with the distance derived from the tamper-proof sensor by comparing the error to a defined threshold. When the error value is above the defined threshold, this may indicate that one or more of the components of the odometer system have been manipulated.",
